    Abstract: PROBLEM TO BE SOLVED: To provide an improved circuit and method for driving a write head in a hard disk drive (HDD) system.
    SOLUTION: The write driver includes a circuit matching output resistance to the odd characteristic impedance of the interconnect and a voltage boosting circuit. The voltage boosting circuit is connected between a high voltage reference or supply voltage and a low voltage reference, and includes a current source, such as a MOS transistor, connected to the input node of a capacitor. During the overshoot duration, the current source operates at saturation to generate a pulsed current with an amplitude of half the load current. The circuit includes another transistor in series with the current generator between the capacitor and the driver output. A forward bias diode is connected between the capacitor output node and high voltage reference and enters reverse bias during overshoot duration swinging the driver output voltage above supply voltage.

    Abstract: PROBLEM TO BE SOLVED: To correct for thermal asperity transients occurring in a hard disk drive.
    SOLUTION: The preamplifier 110 has an input gain stage receiving a signal from an MR head 128, a thermal asperity transient correcting circuit 111, and an output buffer outputting a reader output to a read channel. The thermal asperity transient correcting circuit 111 is composed of a high-pass filter and voltage controlled based upon an input control signal from a filter controller. The filter controller uses a low-pass filter functioning as a peak detector to detect peaks in either the input or output voltage of the high-pass filter. The low pass filter output is applied to a non-linear function generator generating the control signal for the high pass filter based on an increasing function of the absolute value of the low pass filter output.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and a unit offering a high-speed jitter testing capability.
    SOLUTION: The prevention provides an integrated data generator for testing a high-speed serial interface. A transmission timing generator used in a transmit data path includes a high-frequency clock generator such as a phase lock loop and a delay lock loop or the like equipped with an input for receiving an oscillator or a base clock input. A clock modulator receives both of existing low-frequency and high-frequency modulating signals. A high-speed modulating clock signal is generated to allow a jitter testing to be conducted with a receiver combined with downstream. Although a fixed frequency such as 3, 6, 125, 150, 250, 300, 750, 1,500 MHz or the like is used for the high-speed modulating signal for example, any high-speed modulating frequency can be used for generating an intended volume of jitter. In a similar way, the amplitude of the high-frequency modulating signal can be varied as desired.
